Abstract—LEACH is a hierarchy routing protocol for WSN (wireless sensor networks), which is superior to direct communication protocol, minimum-transmission-energy protocol and static clustering protocol. owever, LEACH itself has some defects. In this

I am doing research in wireless sensor network in data aggregation. here cluster head send packet to base station .by using k means cluster algorthim A network is divided into k layer. k cluster are formed in k layer . each cluster has one cluster he

wsn .tcl is genetare the cluster head selection
